I'm quite happy with the present configuration of the braillenote thank you very much! It's true that other note takers have detachable displays, but that's partly because they came out with a voice-only notetaker and added the braile later. I haven't seen any of these units, so really can't say for sure about their construction, but I do know that my braillenote is solidly built and I don't have to worry about parts of it becomming detached from each other.
I've never seen a voicenote so don't know if it is smaller or the same size as a braillenote, nor whether it can be configured for braille as the 18 and 32-cell bn units can be. In otherwords, if you buy a bn-18 you can have that display replaced with a 32-cell display and still retain the original unit. Since I bought my braillenote for the braille display, the only thing I might possibly be interested in would be a detachable speech module, <grin>, but that's highly unlikely. Bottom line "if it ain't broke don't fix it!" Don
